Description

Medicine plaster on eye slow release

Technical field

This utility model relates to the pharmaceutical carrier of a kind of medicine for external use or medicine for external use, specifically medicine plaster on a kind of eye slow release.

Background technology

Traditional ophthalmic administration is main mainly with drop or unguentum, but due to the diluting effect of lacrimal secretion tear, is diluted very soon after general medicine medicine-feeding.Analyze through spot sampling, 3 ~ 5min after the medicine-feeding of medicament for the eyes drop, local drug concentration fall is on average more than 50%, and 10 ~ 15min medicine local concentration is almost nil.This just shows that traditional ophthalmic administration agent type also exists inborn defect, be not enough to provide more lasting drug level supply to eyes local, often cause eye inflammation to be difficult to disappear, this is all the more so for needing the intractable inflammation of comparatively lasting drug level supply.Correlational study shows, in the treatment contrast of intractable trachoma, local uses the patient of chloromycetin drop and uses in patient's contrast of medicine plaster on eye slow release and finds, the lindner's initial body volume atrophy degree of the latter exceedes the former more than 300%.

Utility model content

The purpose of this utility model is to provide medicine plaster on a kind of eye slow release, fundamentally solves the problem that the existing eye medicine for external use drug action time is short, drug effect is poor.It has the advantages such as structure is simple, easy to use, low cost of manufacture.

The purpose of this utility model is achieved in that on this eye slow release, medicine plaster comprises carrier layer, drug-loaded layer, is characterized in that: described carrier layer center is provided with hollow bulb, and carrier layer is made up of some carrier elements be connected by flexible joint; Drug-loaded layer covers on a carrier layer, and matches with carrier layer.

Described drug-loaded layer is provided with the microcellular structure of honeycomb like, and medicine is arranged in microcellular structure.

Described carrier element is two to eight.

The area of described carrier element is identical with shape.

Described carrier layer is made up of polyethylene.

The thickness of described drug-loaded layer is 0.1 ~ 0.2mm.

The width of described flexible joint is 3mm.

The advantage that this utility model has and positive technique effect are: owing to have employed the micropore of honeycomb like structure, and liquid preparation can be trapped in drug-loaded layer under the effect of capillary principle.This paster is applicable to various medicament for the eyes drop, is also applicable to the eye-care in contact lens wearers night.Carrier layer center is provided with hollow bulb, can not block the visual field, does not affect daily work and life during medicine-feeding, and corneal and conjunctiva almost do not have stimulation.Whole paster is flexible design, easier during use paster is implanted eyelid inside.

Detailed description of the invention

Below in conjunction with Fig. 1 ~ 4, describe content of the present utility model in detail by specific embodiment.

embodiment 1

As shown in Figure 1 and 2, on this eye slow release, medicine plaster comprises the part such as carrier layer 4, drug-loaded layer 1.Wherein, carrier layer 4 is the circular sheet-like structures that polyethylene or cellulose polyethylene are made, and its center is provided with hollow bulb 3, looping structure.The corresponding cornea of hollow space, does not affect the local physiological environment of cornea, and avoids covering cornea, is convenient to not affect daily Working Life when medication.Carrier layer 4 is made up of the identical circular vectors unit of two plate shapes, and the flexible joint 2 being 3mm by width between two circular vectors unit is formed by connecting.Drug-loaded layer covers on a carrier layer, and closes with the matching form of carrier element, and drug-loaded layer thickness is 0.2mm.Drug-loaded layer is provided with the microcellular structure of honeycomb like, and medicine is arranged in microcellular structure, and every sheet can receiving medical liquids 0.6 ~ 1.0ml in theory.Owing to adopting flexible joint, by whole paster doubling, storage can be convenient to, and avoid drug-loaded layer to be polluted.

Drug-loaded layer can adopt two kinds of dosage forms, as slow release unguentum or medicinal liquid.If mastic, then in use, directly paster can be placed on below eyelid, afterwards upper eyelid be opened, then paster the first half of doubling is placed between eyeball and upper eyelid, safety extremely easy to use.If medicinal liquid, then need in advance medicinal liquid to be instilled in the honeycomb like structure of drug-loaded layer, the same mastic of using method.

embodiment 2

As shown in Figure 3, another kind of embodiment of the present utility model.Further carrier element can be divided into four identical fan-shaped pasters, make it more fit in eyeball surface.

embodiment 3

As shown in Figure 4, another embodiment of the present utility model.Carrier layer also can be made into other shapes, and as square, hollow bulb shape wherein also can be circle or other shapes, is convenient to produce different types of paster.
